Simplex to duplex copying, is simplified in particular, the requirements are to reverse order the documents for a first pass, place all the documents in a recirculating document handler, move half copies or one sided copies to an auxiliary feed tray, and finally reverse the order of the originals. In another feature, the blank sheets are automatically scheduled and not billed on a customer billing meter.

A duplex extruder head for receiving extrudate from each of two extruders to deliver a composite unitary extrudate such as tire tread stock has a cavity plug or vee-block insert secured in an open top channel-shaped receiver without bolts or hinges by a pair of slidable clamps. The head also has a transverse slot for slidably receiving a die assembly endwise into the slot. The die assembly is then elevated to operating position and securely clamped by a pair of wedge-like gibs. Clamping of eithe...

An automatic pre-collation duplex copier in which original documents having either an odd or even number of pages may be recirculatively copied in reverse serial order yet provide properly collated output duplex copy sets. A simplex/duplex copying system is disclosed in which, when an odd number of document sheets are detected in a first, non-copying, circulation of the document sheets, the copying of the last and subsequent alternate document sheets is inhibited during the first copying circula...

A paper forming fabric having two layers of synthetic weft strands with interwoven synthetic warp strands and approximately 100% warp fill. The upper layer of the fabric comprises a regular array of mesh openings in which the distance between consecutive openings measured in the weft direction is never greater than the thickness of a single warp strand and measured in the warp direction is never greater than the thickness of a single weft strand.

A double-deck connector assembly (1) includes a unitary housing (10) defining upper and lower connection ports (12, 14) with upper and lower central slots (16, 17) for respectively receiving the corresponding upper and lower modules (100, 200) therein. The upper connection port (12) is slightly forwardly offset from the lower connection port (14). A pair of latching arms (20, 22) extend from two opposite ends of each connection port (12, 14) for retaining the corresponding module (100, 200) in p...

A duplex copying machine having a simple and automatic method and apparatus for handling paper at a duplex feeding station in a duplex copier is disclosed. A container for holding a stack of paper is removably connected to the duplex copier at a paper feeding station. The stack of paper is aligned and partially confined within the container by vertically extending surfaces which align the edges of the paper sheets within the stack. Top portions connected to the vertical surfaces extend horizonta...

An aircraft duplex hinge assembly (10 or 10') configured for use in aircraft, especially helicopters, having a compound curvature airframe (130) configuration wherein the edges of access panels (100) and the corresponding airframe apertures have a beveled configuration. The duplex hinge assembly (10 or 10') includes dual hinge mechanisms (20) and a latching mechanism (50) to deactivate the duplex hinge mechanism (10) with the access panel (100) in the closed position. The dual hinge mechanisms (...

A duplex connector 300 is constructed by joining together a pair of simplex connectors 10 --10 using one or more plastic clips 210. Each simplex connector includes a latch 120 for interlocking it with a jack receptacle 40, and each simplex connector includes a pair of pin-receiving holes 103-104, 163-164 on its opposite side surfaces. Each clip includes a first planar structure 211 having a pair of cylindrical pins 203-204, 263-264, having different diameters, in each of two different regions th...

A monopole antenna for aircraft, vehicles, marine vessels and the like comprises a coaxial cable radiator and a metal tube radiator surrounding the lower half of the coaxial cable. The center conductor of a coaxial cable connector applies radiant energy to the jacket of the coaxial radiator. The center conductor of the coaxial radiator extends from the bottom of the cable and is connected to the outer lower surface of the metal tube radiator. In operation, the distributed L-C and R-C values at r...
